CRITICISMS

First, the cost was not the projected 300 cr but actually cost 1,600 cr or about 430% cost overrun.Second, the project was 5 year behind scheduleThird, the supposedly reduction in commute time did not occur. Traffic bunched up at both ends of the Link causing nightmarish grid lock.FOURTH ,The blame rest, as usual, on the notorious Indian corruption and political in-efficiencies.

Compared to China, who in a span of 6 years, completed 7 sea links, under budgets and within the time schedules.15PICTURES
